The root of Michelia is fleshy, and the basin soil is required to have good permeability. The culture soil can be made up of 4 parts of rotten leaf soil, 3 parts of garden soil, 2 parts of rotten manure and 1 part of sand soil.
In summer, the plants with smile should not be exposed to the sun. They should be shaded by 30% to avoid burning the leaves by strong light. They can be placed in the windows and balconies facing east indoors and under the shade or shade shed outdoors. You can see more sunshine after the cool autumn. In winter, it shall be placed indoors in sunny ventilation place.
The lowest temperature for Michelia to survive winter is not lower than 5 ℃. Once the temperature is lower than 5 ℃, the normal physiological activities of the plant will be affected, the absorption capacity of the root will be weakened, and the shoots and leaves of the plant will wilt. At the same time, the maximum temperature should not exceed 15 ℃. If the temperature is too high, the internal nutrient consumption of the plant is too much, which is harmful to the growth of the next year. Therefore, it is better to keep the room temperature between 5 ℃ and 15 ℃ in winter.
Michelia is more drought tolerant and fertilizer loving, and potted plants grow faster. In the growth period and before and after flowering, the plants need more water, which will wither and turn yellow. From March to April, water every 1-2 days, and delay appropriately in rainy days. Water once a day in sunny, hot and dry weather. If necessary, spray water on the leaves and the ground to create a humid environment. In autumn and winter, as long as the basin soil is kept moist, do not water more. Do not use well water to water flowers. The water temperature and soil temperature should be similar. Michelia likes wet environment, but too much water will rot roots, or cause diseases and insect pests. Pour water after the rain.
The application of fertilizer should be fully mature, and should be combined with the application of P and K fertilizer. The basal fertilizer should be applied once before germination of new buds, and the thin liquid fertilizer should be applied once every 10 days in the growing season (April September). Stop fertilization after flowering (October).
In order to make Michelia grow luxuriantly and bloom more, it should be pruned in spring and autumn every year. Michelia has strong hair force, fast growth, and can germinate after being cut off. Generally, when the basin is turned over (from late September to late October in autumn, and from mid March to mid April in spring), pruning should be carried out properly, and then pruning should be carried out after flowering - pruning the overlong branch, the weak branch and the deformed branch. In addition, it can also be pruned into various postures according to the requirements of potted plants.
